Figures for "Towards Improved Satellite Monitoring of Armed Conflicts"

Figure 1. From space, VHR imagery from Planet and Maxar reveals the landscape effects of Russia’s invasion of Ukraine. 1. Cars waiting at the Ukrainian-Hungarian border (Maxar technologies); 2. Active fires in Chernihiv (PlanetScope-2022/03/21); 3a. The North Crimean Channel without water pre-invasion (PlanetScope-2022/02/21); 3b. Filled with water post-invasion (PlanetScope-2022/03/24); 4. Burning apartment buildings in Mariupol (Maxar technologies). Maxar technologies images were obtained from https://www.maxar.com/ on April 5th, 2022. PlanetScope data were obtained under the University of Copenhagen license agreement PL-0030875_2021/2022. Because Maxar and Planetscope original images are commercial they can not be publicly shared but can be requested from the Maxar and Planet with the additional assistance of authors.

Figure 2. A village and surrounding farmland in Ukraine’s Lviv Oblast are more difficult to discern in imagery from medium-resolution civilian Landsat-8 (USGS-2021/05/04) and Sentinel-2 (ESA-2021/05/11) satellites than in imagery from their commercial VHR counterparts (Dove/PlanetScope -2021/05/09 and SkySat-2021/05/09, both of which belong to Planet). Landsat-8 (USGS) and Sentinel-2 (ESA) are available via glovis.usgs.gov. PlanetScope data were obtained under the University of Copenhagen license agreement PL-0030875_2021/2022. SkySat imagery was obtained under special request from Planet.  PlanetScope and SkySat original images are commercial they can not be publicly shared but can be requested from  Planet with the additional assistance of authors.
